Java Software Solutions (8th Edition)

Hi i'm a student at first year. We have the following assignment:

Create a class FavouriteCities.java that contains main method and enum named MyFavouriteCities. It contains a list of cities ordered according to your preference, such as BERLIN (i.e., 1st favourite), NEW_YORK (i.e., 2nd favourite), SYDNEY (i.e., 3rd favourite), etc.; the program should ask you to write a name of a city and then print out the position of the city in your ranking list.

Enter a city:
New York
On the list of your cities, it is on position: 2.

We have to use the material studied so far (Chapters 1 to 3 of Java Software Solutions https://www.amazon.com/Java-Software-Solutions-John-Lewis/dp/0133594955) and I can't get a solution without using if statement.

Very glad if you helping me finding a solution.

I'm stuck after scan:

import java.util.Scanner;

public class FavouriteCities {

    enum MyFavouriteCities{BERLIN, NEW_YORK, ROME, SAN_FRANCISCO}


    public static void main(String [] args)
    {
        MyFavouriteCities city1, city2, city3, city4;

        String city; 

        city1 = MyFavouriteCities.BERLIN;
        city2 = MyFavouriteCities.NEW_YORK;
        city3 = MyFavouriteCities.ROME;
        city4 = MyFavouriteCities.SAN_FRANCISCO;


        Scanner scan = new Scanner(System.in);

        System.out.println("Enter a city:");
        city = scan.nextLine();
        city = city.toUpperCase();
        city = city.replace(" ", "_");


        System.out.println("On the list of your favourite cities, it is on position: "

             + .ordinal() +1);
}}

Thank you Erwin Bolwidt ! It works! The solution I searched for is: System.out.println("On the list of your favourite cities, it is on position: " + (MyFavouriteCities.valueOf(city).ordinal() +1));
